newbie question

[Anon]

If I wan't to find something, and take it out of the context it's in... for example by running uptime and catch the stuff between "up" and "days". How would I do that ??

I'm running BSD, so a cat /proc/uptime is not a good idea... if anyone has a better way of doing the uptime, # of users and load average on BSD I would be happy to hear about it 🙂

<?
$foo = uptime;
ereg('(([0-9]*) day)',$foo,$regs);
echo "This system has been up $regs[2] days without a reboot.";
?>
